00:00Axial Seamount, scientists monitor an active underwater volcano off Oregon.
00:05Axial Seamount swells beneath the Pacific Ocean off Oregon.
00:10This underwater volcano sits on the Juan de Fuca Ridge, where seafloor sensors watch pressure build.
00:16Axial Seamount erupted in 1998, 2011, and 2015, leaving fresh lava flows across the deep seafloor.
00:25Scientists track the volcano with seafloor pressure gauges, earthquake sensors, and underwater cables from the Ocean Observatory's initiative.
00:33Small earthquakes shake beneath Axial Seamount, showing magma moving under the summit caldera.
00:40The seafloor rises as magma inflates the volcano, then drops after an eruption drains pressure below.
00:46Research ships lower instruments into cold Pacific water, collecting data from vents, rocks, and cables.
00:54Hydrothermal vents release shimmering hot water, feeding deep sea microbes, tube worms, and other seafloor life.
01:00Scientists expected a possible eruption around 2025, because inflation and earthquake patterns resembled earlier eruption cycles.
01:09Axial Seamount lies far offshore, so an eruption would mostly reshape deep seafloor instead of threatening coastal towns.
01:17Lava, earthquakes, pressure gauges, research ships, and hot vents make the hidden volcano visible to science.

01:29Yeah, but its a vent the sky is warming up.
